There's probably an easier way to do it, but I'd do something like this with Perl...
Then make it executable and call with
$ my_perl_script.pl my_large_file
This will split your large file into as many 10 data line files (i.e. 11 lines including the header) as required.
Just modify the $NUM_LINES and $HEADER_STRING variables to suit your needs.

ftrylockfile
FLOCKFILE(3) BSD Library Functions Manual FLOCKFILE(3)NAME
flockfile, ftrylockfile, funlockfile -- stdio locking functions
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
void
flockfile(FILE *file);
int
ftrylockfile(FILE *file);
void
funlockfile(FILE *file);
DESCRIPTION
These functions provide explicit application-level locking of stdio FILE objects. They can be used to avoid output from multiple threads
being interspersed, input being dispersed among multiple readers, and to avoid the overhead of locking the object for each operation.
The flockfile() function acquires an exclusive lock on the specified object. If another thread has already locked the object, flockfile()
will block until the lock is released.
The ftrylockfile() function is a non-blocking version of flockfile(); if the lock cannot be acquired immediately, ftrylockfile() returns non-
zero instead of blocking.
The funlockfile() function releases the lock on an object acquired by an earlier call to flockfile() or ftrylockfile().
These functions behave as if there is a lock count associated with each object. Each time flockfile() is called on the object, the count is
incremented, and each time funlockfile() is called on the object, the count is decremented. The lock is only actually released when the
count reaches zero.
RETURN VALUES
The flockfile() and funlockfile() functions return no value.
The ftrylockfile() function returns zero if the object was successfully locked, non-zero otherwise.
SEE ALSO getc_unlocked(3), putc_unlocked(3)STANDARDS
The flockfile(), ftrylockfile(), and funlockfile() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
